Geofence Reminder iOS App

An iOS app that allows users to set geofence-based reminders for points of interest fetched from an API. Built with Swift, MapKit, Core Data, and MVVM architecture.

Overview

This app lets users explore points of interest (e.g., cafes, landmarks) fetched from a mock API, set geofence reminders with custom radii, and receive notifications when entering/exiting the geofenced area. Reminders are persisted locally using Core Data and displayed on a map and in a list.

Features

• API Integration: Fetch points of interest from OpenStreetAPI (https://nominatim.openstreetmap.org/).
• MapKit Annotations: Display locations as custom map pins.
• Geofencing: Set circular geofences (100m–1000m) and trigger local notifications.
• Core Data: Save reminders with location details, radius, and notes.
• Custom Radius Slider: A dynamic circular slider for selecting geofence size.
• Offline Support: Persist reminders and display them without network access.
• Error Handling: Gracefully location permission denials and Notification permission denials.
• Unit Tests: Unit tests implemented

Third-party Libraries

• Alamofire: Used for handling network requests.
• Anchorage: Used for applying constraints in simpler way when creating UI programmatically.
• HGCircularSlider: Customizable circular slider for radius selection.
• IQKeyboardManager: Automatically manages keyboard interactions.

Other Libraries Used

• CoreData: Used to store Geo-fence data
• MapKit: Used to display map and map related data
